CONNECTER Filed July Si)l 1926 Y 2 Sheets-Sheet 2 Patented Oct. 28, 1930 1 UNITED STATES PATENT OFFICE JOHN B. DOWNING', O' ORANGE, NEW JERSEY, ASSIGNOR TO BEAVER MACHINE AND TOOL CO., INC., F NEWARK, NEW JERSEY f ooNNEcrnn Application tiled July 9, 1926. Serial No. 121,373.

The object of m invention is to provide a separable means or attaching a cable consistin of a plurality of wires which form a lura ity of electric circuits to atranslatinglo interlock them in a predetermined relative position. l

A further object is to provide a cable connecter which is simple, economical to manufacture, and to which the various wires comprising the cable may be attached 1n a safe and secure manner.

Attention is directed to the drawings which illustrate the preferred form of my invention in which:

Figure 1 is a cross sectional elevation thru the plug taken on line 1-1 of Figure 2.L

Figure 2 is a plan view of the connecter.

Figure 3 is a cross section thru the connecter taken at right angles to Figure 1, as

along line 2, Figure 2, and shows one half of the plug only, 1t being understood that-the other half is of the same construction.

Figure 4 is a section thru the cap member.

Figure 12 is a side elevation of the female contact member.

Figure 13 is an edge elevation of the male 46 contact member.

Figure 14 is a side elevation of the male contact member. y

To the end that the objects stated may be attained I employ a cap member 1 which is dome shaped and is provided with a central hole 2 for the receptionof a cable. I also employ a body or barrel like member 3, which houses a set of cable terminals. I employ a plug section 4 which also carries a set of cable terminals. The plug member, body member and cap member, are made from any suitable moulded insulation as for example, phenolic compounds, etc.

The plug section 4 is rigidly attached to the translating device by a bracket 5 or equivalent means.

Its purpose is to provide a carrying means for male contact members 6. Y

Referring to Figures 13-14 which show the male contact members (i in detail, 7 is a terminal section for attaching an end of a cable wire to, 8 is a contact section; adjacent the end of the contaet'section 8 is a raised section 9, preferably semi-circular in form which eo-acts with a like raised section 9 in the female contacts 10. 'lhc terminal sei-tion 7 is ben-t at an obtuse angle to the Contact section 8. A boss 1l is coined in the contact section 8 and terminates at the bend which forms the terminal section 7. Approximately midway between the cnd of the terminal section 7 and thc bend a hump like bend l2 is made, the purpose of which will be explained later on. p

Referring to Figures 94() which show the plug member in detail 13 is a body portion and 14 is a flange portion.

The body portion 1.3 has a central hole l5 for a mounting .screwV 16, terminating in a hexagonal pocket 17 for holding ay mounting nut 18. The periphery is divided by he); wa s slots 19-19, etc. which run from the en ,thru the iiange portion 14. Located in radial alignment with the slots lil-19, ete.. and starting midway between the outer sides of the lots in tlie'flange 14 and terminating at the Ebuter ed e of the flange 14 are depressions 20. T ie flan e 14 is provided with eyelet holes 21-21 wiich` are countersunk as at 22-22 for eyelet flanges.

In assembling the contacts 6, to the plug 4, the contact section 8 is assed thru the key slots 19 until the portion midway be tween the bend and the hump 12 rests against the outside of the flange. After all of the contacts 6 are in their respective slots an insulating disc 24 is placed over them and made fast tothe flange 14 by the eyelets 24. As the male contact'is formed with an obtuse angle', the point or end adjacent the raised portion 9 is pressed tightly against the bottom vof the slots. 19 by the pressure ofthe insulating disc 23 bearin on the terminal ortion 7 of the contact. his same pressure orces the bumped bend 12 into the depression 20. .The hump and depression now coactto prevent any tendency of the contact to t out of alignment.

he coined boss 11 acts as a space filler to take up the excess space in the key slot 19 which is relatively much greater than the cross section of the metal forming the spring contact 6. The boss also holds the contact in the correct relationship with the bottom of the slot in which the end adjacent the raised portion 9 Fpresses against.

Referring to igures 7-#8 which show in detail the construction of the body or barrel member 3, 2525, etc., are internal keyway slots for thev reception of female terminals 10. A registering slot 27 interlocks with a registering key 28 on the plug member 4. These registering elements are provided so that the body 3 may be fitted to the plug -4 in one relative position only.

Inserts oreyelets 29 are moulded in one endv of the body portion and are tapped for thev reception of a screw asfwill be explained later on. On the outer eriphery an index boss 30 is formed in ra ial alignment with the key slot 27. The purpose is to indicate readily the position of the key slot 27 when the parts are about to be joined together.

Female contacts 10 are provided with a straightv base portion 31, a foot portion 32 and a resilient portion 33 which is bent at an acute angle to the base ortion 31.` Holes 34 are placed in the end o the resilient portion to provide means for veasily soldering lead wires to the terminal.

An insulating disc 23 is pierced with holes 35-35 etc. These holes are in alignment with slots 19 of the plug member 4 and slots 25 of the body member 3. Slots 36 radiate from either side of the holes 35, etc., and form an aperture for the passage of the resilient end 33 of the contact 10.

Two rivet holes 37-37 are spaced diametrically opposite each other and are of such size as to readily lit over inserts 29 in the body section 3.

The ca member 1, is provided with holes 38-38 also in register with inserts 29. In order to have as much room as possible to house the ends of the cable wires the inside of the cap is relatively large and has bosses 39--39 to form a wall around one side of the holes 23S-38.

So as to obtain a neat ap earance the cap is cut out as at 40-40 Figures 2-3) to form shelves for the hea s of the screws 41-41 to rest on when assembled.

v To form a'unitary structure of the body orl barrel member 3, the contacts 10 are placed in the slots 25 until the foot member 32 rests on the end.i of the barrel, this leaves the extreme ends of the resilient members 33 proJecting out of the barrel for a distance. The insulator disc 23 is litted over the resilient members 33 and vthe inserts 29 which are then spun or riveted over to hold the disc in place.

Referring to Figure 1 it will be evident that the assembled barrel and contacts will lit over the assembled plug and contacts so that the semi-circular raised section 9 on the male contact 6 matches within a like section 9l onth'e female contacts 10 and as the contacts 10 -are resilient the parts will lit together with a snap action.

The cap member 1 is to be slipped over the cable (not shown) before attaching the lead wires of the cable to the contacts 10 at the holes 34. After the attachment is made theeap member is pushed over the cable until it rests on the insulator 23, the screws 41 are then passed thru the holes 38 of the cap and threaded into the inserts 29.

This cable end is then entirely housed within and protected by the cap 1, insulator 23 and barrel 3 and is attached to the live ends of the circuits.

The plug member ma be considered as a distributing block an is housed within the translating device (not shown).

While I have shown and described the preferred form of my invention it will be understood that various forms and modifications are possible Without departing from thespirit of the invention and I do not limit myself to .the exact structures shown.

Having described my invention, I claim:

In a connecter for a multi-circuit cable, ailug member of insulating material provi ed with grooves parallel to its longitudinal axis and having a flange at one end, said flange being provided with holes registering with sai grooves; contact members having a major portion extending thru said h oles and grooves and having a minor portion lying) against the outer face of said flange, a ody member of insulating mate- .rial surrounding said plug member and having grooves parallel to its longitudinal axis;

iis

contacts each havin a. flat portion to rest against one end o said bod member2 a sect1on'at right angles to sai flat portlon extending Within one of said grooves and a resilient section bent back parallel to said fiat portion in contact with one of said first named contacts and extending relatively farther back from said end of said body;

, and a cap member for housinglsaid end.
